The present invention discloses a system for providing real-time validation of text input fields in a Web page during text entry. Such a system can include a validation-enhanced text input element and an input text validator. The validation-enhanced text input element can be configured to contain a validation expression for a text field in a Web page. The validation-enhanced text input element can be contained in the source code document that corresponds to the Web page. The input text validator can be configured to validate a character entered into the text field against the validation expression in real-time. Characters determined as invalid can be visually indicated by the input text validator in the text field.

<script>
  regexs = {};
  regexs['zip']=/\d{5}/;

   style="background-color:white;"
   type="text"
   id="zip"
   onchange="this.style.backgroundColor = (this.value.match(regexs[this.id])) ? 'white' : 'red';"
